Abstract:
Objective:To evaluate the effectiveness of diaphragm ultrasound in predicting the success of extubation from tracheotomy in patients with acquired brain injury.Methods:A retrospective analysis was conducted on 51 brain-injured patients. They were divided into an extubation failure group and an extubation success group. The results of ultrasound examination of the diaphragm in the 2 groups were analyzed by univariate analysis, and the independent variables with significance were further subjected to multivariate logistic regression analysis. R software was applied to build the diaphragm indicators showing significant predictive power into a histogram model. The predictive value of this nomogram model was assessed using the receiver operating characteristics (ROC) curve.Results:The univariate analysis revealed significant differences between the two groups in terms of diaphragm excursion, diaphragm thickening fraction and diaphragm excursion-time index. The multivariate logistic regression analysis and the nomogram showed that those three variables are independent influencing factors predicting the success of decannulation. The areas under the ROC curves confirmed that finding.Conclusions:Diaphragm excursion, diaphragm thickening fraction and the diaphragm excursion-time index are useful independent predictors of the success of decannulation among brain injury patients.
